During deepening of the Mamba South 1 well in Area 4 offshore Mozambique, ENI encountered a new separate pool that contains a potential of up to 7.5 trillion cubic feet (Tcf) of gas in place in clean sands from the Eocene age. The new sequence has about 90 m (297 ft) of gross gas pay and has also been successfully cored.
The gas discovery boosted estimated reserves announced in the exploratory prospectus on Oct. 20 by about 50%. ENI considers that this discovery can lead to a potential of up to 22.5 Tcf of gas in place in the Mamba South Area.
The well will be now drilled to planned total depth of about 5,000 m (16,500 ft). Following completion of drilling, ENI will move to drill the second commitment well, Mamba North 1, located about 22 km north of Mamba South 1 location.
The company has already begun the front-end activities to timely market the gas both internationally and locally.
ENI is the operator of Offshore Area 4 with a 70% interest. Co-owners in the area are Galp Energia (10%), Korea Gas Corp. (10%) and ENH (10% interest carried through the exploration phase).
